Browsing through a pool on a phone is because of the small next/previous buttons really hard. And since there was(at the time) no app that helps there, I thought to myself, I use my mediocre Java skills to create an even more mediocre android app.

So here it is:

It's not finished but as it is able to load pools and show them I thought I share it with you guys.

If you launch it via its icon, you'll find that there is only a "dummy content". To open a pool just open one in Chrome and select "PoolDetailsActivity" in the share menu (or you just press the dummy button and enjoy "Keeping Secrets" over and over again :P). After it loads the pool information click "Open Pool" to view the images. You can pinch to zoom.

If you for some reason want from the picture viewer back to the pool details, use the back button of the phone not the one in the action bar.
